This may be the ultimate version of the ¨twisting the cards¨ theme. When the routine came out it created a sensation. You show a packet of four blue-backed cards. One after the other the blue-backed cards turn face up, the backs of the cards change to red and then to a completely different back design (which in this case are not green backs but World Poker Tour backs.)! Only SIX cards are used! Complete with all the special cards and detailed instructions.
